DB15 Diamond Series: What Makes It the Flagship

Diamondback Firearms April 10, 2026

The Diamond Series represents the pinnacle of the DB15 platform — CMC trigger, Magpul ACS-L stock, and precision-machined components throughout.

The DB15 Diamond Series is our most refined AR-15 platform. Here's what separates Diamond from the rest of the DB15 lineup.

CMC 3.5lb Single-Stage Trigger

The Diamond ships with a CMC drop-in trigger — clean, crisp, and consistent at 3.5 pounds. This is a significant upgrade from the mil-spec triggers in Carbon, Black Gold, and Obsidian.

Premium Furniture

Magpul ACS-L stock for stable cheek weld and battery storage. K2+ grip with overmolded rubber for all-weather control. Skeletonized trigger guard for gloved operation.

Precision S-Rail

Our M-LOK anti-rotation S-Rail provides a rigid, free-floating handguard with full-length top rail and multiple M-LOK slots for accessories.

If you want the best DB15 we make, Diamond is it.
